ASSOCIATION ANALYSIS IN GRAIN SORGHUM (Sorghum bicolor (L.) MOENCH)

The correlation coefficients at genotypic level between eight quantitative characters and path coefficients were estimated in eightyone hybrids and eighteen parents of sorghum. Genotypic correlations clearly established the positive and significant relationship between panicle weight and yield, number of grains per panicle and yield, number of leaves and yield, days to bloom and yield.. The intercorrelation among the yield components were also estimated. Partitioning of the correlation coefficient through path analysis indicated that the direct effect of number of grains per panicle was maximum and positive upon yield and this was followed by 1000 grain weight and days to 50 per cent bloom.
